that are attached to the rock-shalt f. The ends of the lower arms of the elbow-levers f carry rollers or contact-pieces f, that bear upon suitable cams, F, that are carried by the cam-shaft there being one cam F for each leverf"-. (See Fig. 10.) The rollers or contact-pieces f are presz'ed against their re speetive cams F by means of springs f, that are secured at one end to the levers f and at their opposite ends to the framing of the machine. The action of the springsf' and cams 1 serves to give the sin ker-bar f, through the medium of the levers f'-, a short reeiprotatting motion that is nearly horizontal.

The above construction of parts is substantially similar to that shown in the aforementioned application, No. 189,238. In that application, however, the sley is carried by a stationary bar secured to the framing.

In the accompanying drawings, the letter '1' represents the sley. This sley is in the form of comb-teeth that project from a bar, The opposite ends of the teeth of the sley 1' pass into and are seen red to the sinker-barf". The needles (1* pass through the sley i, between the comb-teeth thereof, and between the sinker-bar f and the comb-bar as clearly shown in l igs. l and t). In Fig. 2 the bar 1'? is removed, showing the sley and sinker teeth lfletwveen the needles. erably curves dmvnwm'd and .t'orms a bed upon which the work rests. The sley is of such width that when it is moved inward by the sinker-bar it will still be beneath the work. Above the sley i are sinkers f", for knocking over the loops formed on, the needles. The sinkcrs f are sepz'trate strips of metal that are passed into the si nker-ba r f and suital'ily held therein. These sinkersf project from the barf in the tornrot' combteeth; but each sinker, being separate, can be readily removed and replaced in case of accident or for other cause. The needles ('Z pass between the sinkers f and rise and fall in the sley 1', said sinkers acting to secure the loops formed on the bearded needles.

As many loi'igitudinal guide-bars g" as are required are guided in forked arms that are ad justably attached to the ends of [orward-be'nt levers g, which levers are secured The n ide-bars g are supported on the levers g and arms by pins 9, that are carried by the guide-bars, which pins pass through holes in the lovers This sley 1' pref- 1 g and arms shown in lt igs. 1, 2, 1t), and 11. The arms 9 adjacent to the holes that receive the pins y", have slots 9 as shown. Screws or bolts pass through the slots 1 and into or through the levers g, and serve to hold the arms in position on the levers r 11y means of those slots and screws the arms may be turned on their pins or pivots r so as to tip the guide bars f with relation to the needles.

The guide-bars receive endwise motion by the hillowing means: At one end each guideharg is secured to a spring, 5-, (see Fig. 2,) the opposite ends of said springs being secured to the framing. The opposite endot each guidebar is connected by a rod, to the upper end ot a lever, g, as shown in Figs. 2,10, and l l. The levers g oscillate on the fulcrum 9 while their lower pointml ends bear on studwheels g, carried by a shaft, 9", that is joue nailed in the training.

To the ci rctnnterenee ol the wheels g are secured as many rows of studs 9* as there are levers o'-one row for each lever. These studs g" pass into the wheels g and are secured in place by means of set' screws r "one For each stud.

The studs g may be of various sizes or placed at different distances apart, so as to [form the different camsurfaces required to give proper endwise motion to the guide-bars g". The studs of each row act to give motion to one of the levers g" and one ot' the guidebars To the shaft 5 is also keyed a \vorni-\\'lieel, g that receives motion from a worm, g 1 hat is keyed to the canrshai't As the camshaft rotates,the stud-wheel through the gearing and g, will be rotated. This i1nparts, by the studs on the circuinference oi the same, motion to the l'ulcrumed levers g" to move the guide-bars g" in one direction, the springs .5- moving the guide-bars in the opposite directirm. Said springs s, by their tensitm on the bars g, also act to keep the ends of the levers g pressed against the studwheel g. I 3y this means lon gitudin all y-reciproeatingmotion is given to the guide-bars g Any desired number of guide-bars and their operatirig-levers and rows of studs may be used. The above parts, excepting the slotted arms 5 are suhstz'mtially similar to those in the before-mentioned applitation.

Besides the endwise motion imparted to the guideliars g" by the stud-wheels g and sprii'lgs .9, they receive a backward-a1id-forward or latierally-oscillating motion by in cans of lovers that are each secured at one end to the rock-shaft; g. The levers g are slotted at their free ends and are (,O'llllOC'i'Otl to the upper arms of bell-crank levers g. These levers g are mounted loosely on the needle-bar rock-shaft (Z, and are slotted at their upper ends or those ends that are connected to the levers g. The slots of both levers, g and .g, are placed side by side, and a spindle, g

is passed through both slots.

A square piece of metal, g", is screwed on one end of the spindle and nicely fitted in the slot of lever and the opposite end of the spindle g is then secured to the slotted end of the lever by a lock-nut or other means.

is a roller or contact-piece placed on the spindle or carried by the upper arm of the lever g. This roller or contact-piece rides on the surface of the guide-bar cam G.. The lower arm of the bell-crank lever g also carries a roller or contact-piece, g, which rides upon the surface of the guide-bar counter-cam G. By the described construction of the levers g and g and their connection at the slot-ted ends the laterally-oscillating motion of the guide-bars can be extended or reduced by moving the spindle g and metal piece g" along in the slots of the levers g g and securing them by means of the lock-nut on the axle g.

Above the machine the necessary beamtackle, K, is provided to receive the beams of yarn K to supply the needles. Below the sinkers and sley a roller, j, is provided to receive the fabric.

The several movements of the parts are as follows: The needle-bar d rises vertically about half its motion. The lapping of its threads upon the needles is then made by the guide-bars g", which are moved to and fro by means of the levers g, g, and g, actuated by the cams G G, and longitudinally by the springs s, rods g, levers g, and stud-wheels The needles then rise to their full extent to pass the laps under the beards of the needles. Then they descend, and just as the beards of the needles enter the sinkers j" the presser-bar c presses the beards into the eyes of the needles and the work is then knocked over. The sinkers f then move back and forward, in order to secure the last loops made, at the same time moving the sley 2', which always remains under the work.

The needles and other parts of the machine may be arranged to work either vertically, as shown, or horizontally, or in any other position, if desired, and the terms vertical and horizontal, as applied to these parts, are only used to render their relative positions and movements clear.

e are aware that it is old to secure the presser-bar to the bar that carries the points or sinkers. This is shown in United States Patent No. 251 ,184, December 20, .lSSLwherein the prcsser-bar takes all the movements and vibrations of the sinker-bar; but it is new with us to make the presser-bar independent of the sinker-bar and to give it independent movement. By this means we can move the Presser-bar atany desired moment, and we reduce to a minimum the friction on the threads that is caused by the movement of the presser-bar in unison with the sinker-bar. By using our independent presser-bar we are enabled to work the machine faster and to use finer threads than has heretofore been done.

Having now described our invention, what we claim is 1. The combination of the vertically-movable needle-bar cl, having bearded needles, levers (Z carrying said needle-bar and cams D, horizontally-reciprocating independent and. separate presser-bar e, rockshaft e, levers 6 carried by the shaft 9 and supporting the separate presser-bar e and cam E, for actuating the levers 0 separate and horizontally-movable sinker-bar f, carrying points f and the comb-like sley i, that is secured to the bar f below the point f shaft f, levers f carrying the separate sinker-bar f and cams F, and the longitudinally and laterally movable guide-bars g, with mechanism, substantially as described, for moving said guide-bars, all as specified.

2. The combination of a needle-bar having bearded needles, levers (Z and cams D, for supporting and moving said needle-bar, a separate and independent presser-bar, rockshaft (2, levers 6 carried by the shaft and supporting the ii'ldependent presser-bar and cams E, for giving independent movement to the 1n'esser-bar, and a separate sinkerbar carrying the sinkers, and carrying also the sley separate from the said sinkers, shaft f and levers carrying said sinker-bar and cams F, a shaft carrying the cams and guide- .bars, and mechanism, substantially as described, by which an endwise or longitudinally-reciprocatin motion and lateral motion is impart ed to the guide-bars, substantially as set forth.

The combination of the guide-bar rockshaft g, levers g, having forked arms 9 guidebar g", guided by said arms and levers, lever g having slotted end, elbow-lever having slotted upper end, spindle g slidepiece g, carrying said spindle and guided in the slotted ends of the levers, and cam-shaft C, having cams G G, substantially as set forth.

at. The combination of the levers g, guidebar arms 9 carried thereby, said arms having slots, screws 9 for said slots, and guide-bars g guided in the arms and having pins that pass through the levers g and arms g all arranged so that the arms g may be turned to tip the guide-bars, substantially as herein shown and described.

In testimony that we claim the foregoing as our invention we have signed our names in presence of two subscribing witnesses.
